Socio-demographic, health and drug use characteristics among people with different frequency patterns of cannabis use in Brazil

We undertook a cross-sectional internet-based survey assessing socio-demographics, cannabis use frequency, other drug use, quality-of-life (QOL), affective states (i.e. anxiety and depression), and cannabis use disorder among adult respondents in Brazil. A multinomial logistic regression was conducted using cannabis frequency status as the dependent variable. A to…
Suicide Attempts Among French and Brazilian Adolescents Admitted to an Emergency Room. A Comparative Study of Risk and Protective Factors
Despite presenting similar psychopathologies, Brazilian adolescents presented a more insecure attachment style and used the religious kind of coping more commonly than their French counterparts. We hypothesize that religion may compensate for the social vulnerabilities present in a middle-income country such as Brazil. More transcultural studies may help to elucidate this phenomenon
Treating drug dependence with the aid of ibogaine
Substance use disorders are important contributors to the global burden of disease, but current treatments are not associated with high rates of recovery. The lack of approved and effective treatments is acutely problematic for psychostimulants like cocaine and crack cocaine. One promising alternative in the treatment of drug dependence in general and psychostimulants in particular is the use of the psychedelic alkaloid ibogaine combined with psy…

Two screening tools were used: the Short Alcohol Dependence Data (SADD) and the CAGE questionnaires. In this sampl…

Ayahuasca in Adolescence
The purpose of the study was to evaluate neuropsychologically adolescents who use ayahuasca in a religious context. A battery of neuropsychological tests was administered to adolescents who use ayahuasca. These subjects were compared to a matched control group of adolescents who did not use ayahuasca.

Ayahuasca in Adolescence
Ayahuasca is believed to be harmless for those (including adolescents) drinking it within a religious setting. Nevertheless controlled studies on the mental/ psychiatric status of ritual hallucinogenic ayahuasca concoction consumers are still lacking. In this study, 40 adolescents from a Brazilian ayahuasca sect were compared with 40 controls matched on sex, age, and educational background for psychiatric symptomatology. Screening scales for depr…

Ritual use of ayahuasca within the context of the Brazilian ayahuasca churches often starts during late childhood or early adolescence. Premature access to psychoactive drugs may represent a risk factor for drug misuse. Conversely, religious affiliation seems to play a protective role in terms of substance abuse. The objective of this study was to describe patterns of drug use in a sample of adolescents using ayahuasca within a religious setting.…
